Title: Edge bearing plate in rotary sheet punching device
Inventor: TAKEUCHI TAKAYUKI
IPC: B26F1/38
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To easily and elastically deform a metallic plate along the outer periphery of an anvil cylinder by forming a plurality of punch holes in the remaining part except a location opposed to a sheet punching edge of the metallic plate. SOLUTION: Because a metallic plate 8 is extremely difficult to elastically deform when thickness of the metallic plate 8 is about 1 mm when a edge bearing plate 7 is mounted and a contact angle with an anvil cylinder becomes small by elasticity of the metallic plate 8 itself, a case where a sheet can not be accurately punched is generated. Therefore, punch holes 24 are formed in the remaining part except a location opposed to a punching blade and crease of the metallic plate 8. When the punch holes 24 are provided at the location opposed to the punching blade and crease at this stage, the punching and creasing of the sheet become incomplete. As a result, the metallic plate 8 can be easily and elastically deformed along the outer periphery of the anvil cylinder, even if the plate 8 is thick, and a setting work of the edge bearing plate 7 can be facilitated.
